Web Basics

World Wide Web (WWW): An information system interlinked by hyperlinks, where resources are accessed using URLs.
Web Page: Individual HTML documents containing text, images, and multimedia.
Web Browsers: Software for accessing web pages (e.g., Chrome, Microsoft Edge, Safari).
Web Servers: Serve web pages to users via the HTTP protocol (e.g., Apache HTTP Server, Node.js).

Key Concepts

HTML (Hypertext Markup Language): Encodes documents with hyperlinks; viewed using a browser.
URL (Uniform Resource Locator): Identifies documents/resources on the internet, formatted with a protocol, domain, and resource path.
HTTP (Hypertext Transfer Protocol): Protocol for web communication; facilitates requests from clients to servers.

MIME (Multipurpose Internet Mail Extensions)

MIME specifies the document format sent by the server to the browser, ensuring correct processing of the data.
MIME types include text, image, and video formats.

HTTP Protocols

URL actions involve sending requests to servers using GET and POST methods.
GET: Limited data transmission visible in the URL; not secured.
POST: Secure data transmission, suitable for larger data sets.

HTTP Request and Response

Requests are sent by the client to the server, with the server returning data wrapped in an HTTP response header.
HTTP Response Codes:
- 100 Continue: Part of request received.
- 200 OK: Request succeeded.
- 403 Forbidden: Access denied.
- 404 Not Found: Resource not found.
